Sounding Rockets Launch from the Marshall Islands

Red and white vapor clouds filled the skies over the Marshall Islands as part of NASA’s Equatorial Vortex Experiment (EVEX). The red cloud was formed by the release of lithium vapor and the white tracer clouds were formed by the release of trimethyl aluminum (TMA). via Pocket http://www.nasa.gov/multimedia/imagegallery/image_feature_2504.html
